About this role

Location: Remote (Europe)
Employment: Full-time

🌐 About Our Client

Our client is building a cutting-edge AI-powered cryptocurrency trading platform. The product delivers automated trading bots (DCA, Grid, Quantum), portfolio management tools, real-time market data, and multi-exchange integrations (Binance, Bybit, OKX, and others).

Their mission: to provide institutional-grade trading capabilities with consumer-grade UX — making advanced trading accessible, fast, and reliable.

💻 What You’ll Do

As a Frontend Engineer, you’ll be at the center of creating an intuitive, high-performance trading experience:

Ship real-time trading features in React 18+ with TypeScript.
Design data flows with Redux Toolkit, Redux-Saga, and React Query (caching, optimistic updates, real-time sync).
Integrate APIs & live feeds via REST + WebSockets for order books, balances, and notifications.
Craft responsive UIs with Tailwind CSS + Styled Components, ensuring a seamless mobile-first experience.
Deliver rich visuals like candlestick charts, P&L dashboards, and live market visualizations using ApexCharts or similar.
Optimize performance with code-splitting, lazy loading, bundle budgets, and profiling.
Implement secure auth flows (JWT, OAuth, 2FA) and manage exchange API keys safely.
Contribute to internationalization (13+ languages, including RTL).
Raise the bar by mentoring peers, reviewing code, and shaping front-end architecture.

🧑‍💻 You’ll Be a Strong Fit If You Have

Solid expertise in React (18+) + TypeScript and modern ES2020+.
Hands-on experience with Redux Toolkit, Redux-Saga, and React Query in production.
Proven work on real-time systems (WebSockets, live market data, large datasets).
Experience with charting libraries (ApexCharts, Highcharts, D3, etc.) including live updates.
Strong understanding of performance optimization.
Awareness of secure authentication flows and API key management.

Leveling guidance:

Mid-level: ~3–5 years React/TS experience.
Senior-level: 5+ years with architectural or product-wide impact.
👉 Impact > years of experience: if you can demonstrate senior-level contributions, you’ll be considered at that level.

✨ Bonus Skills

Trading/fintech background (order forms, risk, real-time systems).
Testing with Jest + React Testing Library.
Familiarity with CI/CD pipelines.
Monitoring/analytics (Sentry, Datadog, PostHog).
Experience with PWAs or Web3/wallet integrations.

🤝 What Makes You Stand Out

Problem-solving mindset in complex, data-heavy contexts.
Collaborative and proactive in Agile teams.
Clear communication, clean documentation, thoughtful peer reviews.

📈 What Success Looks Like

You’ll deliver high-impact features for a global trading audience, ensure the platform is fast, reliable, and secure, and shape the front-end architecture of a product scaling at speed.
